INTERVENÇÃO NO CÓRREGO DO ROSÁRIO EM PARAGUAÇU-MG: Uma solução para enchentes e inundações

Abstract

This work proposes a process of channeling the Rosário Stream, located in the city of Paraguaçu, which faces significant challenges related to flooding due to its proximity to bodies of water. Rapid urban growth, lack of planning, and obstruction of watercourses contribute to devastating events, impacting the economy, properties, health, and access to essential services. Given this scenario, the proposed intervention focuses on modifying the local stream, addressing issues such as rainfall, soil permeability, the state of the stream, and flood prevention strategies. The objectives include the study of rainfall, mapping of soil permeability, analysis of the state of the stream, and development of flood prevention strategies. The theoretical framework addresses urban floods in Brazil, the hydrological cycle, environmental consequences, and the municipal legislation of Paraguaçu. The proposed intervention measures include the channeling of the stream, with an emphasis on the use of concrete channels. The proposal aims to improve the efficiency of the local stream’s flow, adopt sustainable practices, and promote popular participation, aiming for a more resilient and safe city for future generations. The results indicate that the planned channeling can significantly reduce the occurrence of floods, improving the drainage capacity and the environmental quality of the stream. The diagnoses carried out showed high rainfall variability and low soil permeability, confirming the need for structural interventions. The project budget was divided into four main stages, totaling R$ 4,119,172.87. The schedule of the budget stages for the execution of the project is divided into four stages: the first stage lasts 9 days, the second stage 10 days, the third stage 18 days, and the fourth stage 300 days. It is concluded that the implementation of the proposed measures will not only mitigate flood risks but also provide socioeconomic and environmental benefits for the Paraguaçu community. .
